  Hereinafter, embodiments of the present invention will be described based on the drawings.

[Basic configuration]
FIG. 1 is a schematic view showing an example of a gaming machine island 1 according to an embodiment of the present invention. The gaming machine island 1 has a frame 100 built on the floor of the gaming hall, a plurality of gaming machines 200, a lower tank 7, an out ball inserting rod 8, an out ball guiding rod 8a, an island rod 9, and And a game medium circulation mechanism provided with the polishing device. A large number of gaming machines 200 are back-to-back, juxtaposed along the front and back, and housed in the frame 100. Hereinafter, the gaming machine 200 will be described as a pachinko machine and the gaming medium will be described as a gaming ball (pachinko ball). Here, the horizontal direction in which the gaming machines 200 are juxtaposed is referred to as "longitudinal direction" or "X direction". Further, a horizontal direction orthogonal to the longitudinal direction is referred to as a "short direction". In addition, a direction perpendicular to both the longitudinal direction and the short direction is referred to as "height direction".

  The frame 100 includes, from the top, a curtain plate 101, a storage frame 102, a roof plate (also referred to as a top plate) 103, a waist plate 104, and a baseboard (not shown). The gaming machine 200 is stored in the storage frame 102. The gaming machine 200 is placed on the roof plate 103. Here, a space between the front plate 101 and the rear plate 101 of the gaming machine island 1 may be referred to as an upper space. In addition, there is a case where the space below the weir plate 103 and the space between the front waist plate 104 and the rear waist plate 104 may be referred to as a lower space.

  The lower tank 7 is provided in the lower space. The game balls used in the game machine 200 (referred to as "out balls") are inserted into the lower tank 7 through the out ball insertion rod 8. The out ball put into the lower tank 7 is transferred to the center of the gaming machine island 1 through the out ball induction rod 8a.

  The pumping and polishing apparatus 10 is configured to polish and lift the gaming balls by pumping them while stirring the gaming balls and the abrasive. The abrasive is a particle made of resin and is porous, and can remove dirt of the gaming ball by stirring with the gaming ball.

  FIG. 2 is a front view of the lifting and polishing apparatus 10. As shown in FIG. 1 and FIG. 2, the pumping and polishing apparatus 10 has a main body 2 and an on-island tank 3 and is provided at the central part of the gaming machine island 1. The pumping and polishing apparatus 10 pumps up and transports the gaming balls transferred to the center of the gaming machine island 1 and stores the pumped gaming balls in the island tank 3. The game balls stored in the island tank 3 flow down to each game machine 200 through the island boat 9. As described above, the gaming medium circulation mechanism circulates the gaming balls inside the gaming machine island 1 and is configured to be reusable.

  The main body 2 has a base 4 fixed at a predetermined position of the game arcade, and a support 5 erected on the base 4. The on-island tank 3 is provided at the top of the support 5.

  The transfer means 40 comprises a helical screw member 41 (only the axis is shown in FIG. 2) inserted into the cylindrical body 30 and a motor 42 for rotating the screw member 41 in the cylindrical body 30. . By rotating the screw member 41 in a predetermined direction, the gaming balls and the abrasive are transferred from the merging portion 31 toward the upper side of the island tank 3 while being stirred in the cylinder 30, and during this time the gaming balls are polished by the abrasive Be done. The transferred game balls and abrasives flow from the upper end of the cylinder 30 to the separating means.

  The height from the cylinder axis of the lower end portion (linear cylinder 320A) of the cylindrical body 30 to the upper edge of the waist plate 104 is hereinafter referred to as "the waist plate height H". The height of the gaming machine 200 placed on the roof plate 103 is substantially constant between the gaming machine islands 1. The height H of the waist plate 104 is substantially constant among the gaming machine islands 1 because the height of the heel plate 103 is also the height of the upper edge of the waist plate 104. In the following description, the height H of the lumbar plate 104 is fixed. Further, the height from the lumbar plate 104 to the on-island tank 3 is made constant. The cylindrical shaft of the linear cylinder 320A is at a predetermined height from a predetermined position of the game arcade to which the base 4 is fixed.

  The cylindrical body 30 is disposed above the height H of the waist plate 104, and has an upper cylinder 310 whose cylinder axis stands substantially vertically, and a lower cylinder 320 disposed below the height H of the waist plate 104. The island upper tank 3 is connected to the upper end portion of the cylindrical body 30. Since the height from the lumbar plate 104 to the island tank 3 is constant, the upper cylinder 310 which is disposed above the height H of the waist plate 104 and whose upper end is connected to the island tank 3 has the same length among the gaming machine islands 1 Have That is, the island tank 3 is commonly used among the gaming machine islands 1.

  At the lower end portion of the cylinder 30, there is provided a junction having a predetermined width for receiving the gaming balls used in the gaming machine 200 and the abrasive for polishing the same, and a joining portion 31 to be joined at the clearance is provided. The position RP at which the merging portion 31 is provided is an example of the “position for receiving gaming media”. The length LA from the position (position in the X direction) of the cylinder axis of the upper cylinder 310 to the position RP differs depending on the gaming machine island 1. The lower cylinder 320 has a length LB which is a distance (full length) along the cylinder axis between its both ends according to the length LA (the gaming machine island 1). That is, the pumping and polishing apparatus 10 according to the present embodiment prepares the plurality of lower cylinders 320 having different lengths LB, so that even if the position RP for receiving game media changes, the lower cylinder 320 is placed at that position RP. Since the position of the confluence part 31 in can be matched, it can respond to multiple types of length LA. Here, “type” is determined in accordance with the length and the bending radius R (described later), and is not determined in accordance with other factors such as the material.

Next, when multiple types of lower cylinder 320 corresponding to multiple types of length LA are prepared, it will be described how the lift polishing apparatus 10 is configured.
FIG. 3 is a front view of the lifting and polishing apparatus 10.
As shown in FIG. 3, the lower cylinder 320 is a linear cylinder 320A having a length L in the longitudinal direction (X direction) extending substantially horizontally from the position RP toward the lower part of the upper cylinder 310, and one end is a linear cylinder It has a curved cylinder 330 bent at a bending radius R at the cylinder axis, connected to 320 A and gradually bent from one end side and connected to the lower part of the upper cylinder 310. The straight cylinder 320A is disposed between the receiving cylinder 321 having the length L1 and the joining cylinder 31, and the receiving cylinder 321 and the curved cylinder 330, and the longitudinal direction (X And a relay cylinder 322 having a length L2 (axial length). The upper cylinder 310 may be referred to as a “first cylinder”, the straight cylinder 320A may be referred to as a “second cylinder”, and the curved cylinder 330 may be referred to as a “third cylinder”.

  Next, steps of assembling the cylindrical body 30 will be described with reference to FIGS. 3 and 4. FIG. 4 is a flowchart showing the steps of assembling the cylinder 30. As shown in FIG.

<Preparation stage>
In the preparation step shown in step S101 of FIG. 4, an upper cylinder 310 having the same length and a plurality of lower cylinders 320 having different lengths LB are prepared.
The preparation of the lower cylinder 320 will be described with reference to FIG. FIG. 3 shows the length L3 from the position RP to the other end (right end in FIG. 3) of the receiving cylinder 321, and the length L4 from the position RP to one end (left end in FIG. 3) of the receiving cylinder 321. . Further, the height H from the cylinder axis of the straight cylinder 320A to the upper edge of the waist plate 104 is shown. In addition, when the plurality of types of lower cylinders 320 having different lengths LA are prepared, the same one is prepared for the receiving cylinder 321. The length L1, L3 and L4 will be described below as constant. Further, the height H will be described as being constant.

As shown in FIG. 3, the relationship between the length LA from the position (position in the X direction) of the cylinder axis of the upper cylinder 310 to the position RP and the length LB of the lower cylinder 320 is given by the following equation (1) expressed.
LB = L4 + LA + πR / 2 + H-2R (1)
Moreover, length LA is represented by following Formula (2).
LA = L2 + L3 + R (2)
The following can be understood from the fact that the equations (1) and (2) and the lengths L3 and L4 and the height H are constant (described above). That is, if the length LA changes in accordance with the position RP of the gaming machine island 1, preparing the plurality of lower cylinders 320 having different lengths LB corresponds to the position RP of the gaming machine island 1 Can.

  In order to prepare a plurality of types of lower cylinders 320 having different lengths LB, any of the following (1) to (3) may be prepared. (1) Prepare multiple types of relay cylinders 322 having different lengths L2 (hereinafter referred to as the first preparation). (2) A plurality of types of curved cylinders 330 having different bending radii R are prepared (hereinafter referred to as a second preparation). Further, (3) a plurality of lower cylinders 320 having different ratios of the length L of the straight cylinder 320A to the bending radius R are prepared (hereinafter referred to as the third preparation).

The length L is expressed by the following equation (3).
L = L1 + L2 (3)
Further, the ratio between the length L and the bending radius R is expressed by the following equation (4).
L / R = (L1 + L2) / R (4)

Next, the first to third preparations will be described.
(First preparation)
A receiving cylinder 321 having the same length L1 is prepared. Preferably, the length L1 is about 41 cm, which is shorter. The short receiving cylinder 321 has the following advantages.
The length L1 of the receiving cylinder 321 is determined by an opening (described above) having a predetermined width for receiving gaming balls and the like. In other words, by securing the opening of the required width and preparing a shorter receiving cylinder 321, the length L3 of the position RP also becomes shorter from the right end, and the length L3 and the length L2 of the relay cylinder 322 The length LA, which is the sum of the bending radius R of the curved tube 330, is also shorter. In particular, when the relay cylinder 322 is not used (L2 = 0 mm), the length LA is the shortest. The lower cylinder 320 can be applied to the gaming machine island 1 in which the short length LA is short.

Furthermore, a plurality of relay cylinders 322 having different lengths L2 are prepared. The length L2 is preferably about 480 mm or less because the number of combinations with the bending radius R of the curved cylinder 330 increases.
Furthermore, a curved tube 330 having the same bending radius R is prepared.
Furthermore, the upper cylinder 310 having the same length is prepared.

Next, an example of the first preparation will be described. The length L1 = 407 mm, the length L3 = 150 mm, and the bending radius R = 250 mm are made constant.
The length L2 (= 0 mm, 120 mm, 240 mm, 360 mm, 480 mm), the length L3 (= 150 mm), and the bending radius R (= 250 mm) are substituted into the above equation (2).

The length LA is 640 mm (= 240 mm + 150 mm + 250 mm).
The length LA is 760 mm (= 360 mm + 150 mm + 250 mm).
The length LA is 880 mm (= 480 mm + 150 mm + 250 mm).
That is, by preparing five types of relay cylinders 322 having different lengths L2, it is possible to cope with five types of lengths LA.

  The first preparation described above is an example, and the length L2 of the relay cylinder 322 is not limited thereto, and the length LA is not limited thereto. In short, by preparing the relay cylinder 322 having a plurality of types of lengths L2, it becomes possible to cope with a plurality of types of lengths LA. The length L2 includes 0 mm. At this time, preparation of the relay cylinder 322 is unnecessary.

The bending radius R is preferably about 250 mm or more in terms of the degree of bending of the screw member 41 inserted into the cylindrical body 30 or the shape of the cylindrical body 30 itself, and the length of the relay cylinder 322 It is preferable that it is about 250 mm from the fact that the combination with L2 increases. The bending radius R is preferably equal to or less than the height H of the waist plate 104 (R ≦ H). The reason is that the curved tube 330 is accommodated in the lower space (described above) below the height H of the waist plate 104. Moreover, it is for leaving the linear part (The range of (HR) shown in FIG. 3) which is a part which connects the upper cylinder 310 and the lower cylinder 320. FIG.
Furthermore, the upper cylinder 310 having the same length is prepared.

Next, an example of the second preparation will be described. Note that the length L1 = 407 mm, the length L2 = 0 mm, and the length L3 = 150 mm are constant.
The length L2 (= 0 mm), the length L3 (= 150 mm), and the bending radius R (= 250 mm, 370 mm, 490 mm, 610 mm, 730 mm) are substituted into the equation (2).

The assigned results are shown below.
The length LA is 400 mm (= 0 mm + 150 mm + 250 mm).
The length LA is 520 mm (= 0 mm + 150 mm + 370 mm).
The length LA is 640 mm (= 0 mm + 150 mm + 490 mm).
The length LA is 760 mm (= 0 mm + 150 mm + 610 mm).
The length LA is 880 mm (= 0 mm + 150 mm + 730 mm).
That is, by preparing five types of curved cylinders 330 having different bending radii R, it is possible to correspond to five types of lengths LA.

  The second preparation described above is an example, and the bending radius R of the curved cylinder 330 is not limited thereto, and the length L2 of the relay cylinder 322 is not limited to 0 mm.

Furthermore, the upper cylinder 310 having the same length is prepared.

Next, an example of the third preparation will be described. In addition, length L1 = 407 mm and length L3 = 150 mm are made constant.
L / R = (L1 + L2) / R (4)
The length L2 (= 0 mm, 110 mm, 220 mm, 350 mm, 480 mm) and the bending radius R (= 250 mm, 260 mm, 270 mm, 260 mm, 250 mm) are substituted into the above equation (4).

The assigned results are shown below.
The length LA is 400 mm (= 0 mm + 150 mm + 250 mm).
L / R at this time is approximately 1.6 (= (407 mm + 0 mm) / 250 mm).
The length LA is 520 mm (= 110 mm + 150 mm + 260 mm).
L / R at this time is approximately 1.9 (= (407 mm + 110 mm) / 260 mm).
The length LA is 640 mm (= 220 mm + 150 mm + 270 mm).
L / R at this time is approximately 2.3 (= (407 mm + 220 mm) / 270 mm).
The length LA is 760 mm (= 350 mm + 150 mm + 260 mm).
L / R at this time is approximately 2.9 (= (407 mm + 350 mm) / 260 mm).
The length LA is 880 mm (= 480 mm + 150 mm + 250 mm).
L / R at this time is about 3.5 (= (407 mm + 480 mm) / 250 mm).
That is, by preparing the combination of the relay cylinder 322 and the curved cylinder 330 which are five types of L / R, it is possible to correspond to five types of lengths LA.

In addition, the combination of the following cylinder 322 for relay and the curved cylinder 330 may be sufficient as LA = 880 mm.

That is, for the upper spiral 411, the upper spiral 411 having the same length is prepared. On the other hand, with regard to the lower spiral 412, plural types of lower spirals 412 having different lengths are prepared.

(Upper spiral 411)
7A is a front view of the upper spiral 411, FIG. 7B is a side view of the upper spiral 411, and FIG. 7C is a C arrow view when the upper spiral 411 is viewed in the direction along the spiral axis. As shown in FIGS. 7A to 7C, the upper spiral body 411 is formed by winding a thick wire having a width of about 13 mm and a thickness of about 6 mm into a large diameter (about 65 mm outer diameter and about 39 mm inner diameter). The shaft 43 is fitted to the inner diameter portion of the upper end portion of the upper spiral body 411. The winding pitch of the upper spiral 411 is 50 mm.

(Lower helix 412)
FIG. 8A is a front view of the lower spiral 412, and FIG. 8B is an arrow view as viewed in a direction along the helical axis of the lower spiral 412. As shown in FIGS. 8A and 8B, the lower spiral body 412 is formed by winding a thin wire having a width of about 10 mm and a thickness of about 4 mm into a small diameter (about 58 mm outer diameter and about 38 mm inner diameter). The winding pitch of the lower spiral 412 is 40 mm. The winding direction of the wire is the same in both the upper spiral 411 and the lower spiral 412.

(Connection of upper spiral 411 and lower spiral 412)
The upper spiral 411 and the lower spiral 412 are linked as follows.
First, the upper spiral 411 used in common among the gaming machine islands 1 is prepared. Subsequently, a lower spiral 412 of a type having a length corresponding to the length LB (or length LA) of the lower cylinder 320 is prepared.

  Next, the ends of the upper spiral 411 and the lower spiral 412 are connected. FIG. 9A is a front view showing a state in which the end portions of the upper and lower spirals overlap each other, FIG. 9B is a cross-sectional view taken along line VII-VII in FIG. 9A, and FIG. It is an enlarged front view which shows the state when the edge parts of are piled up.

  As shown in FIGS. 9A, 9B and 10, the lower end of the upper spiral 411 (left end in FIG. 9A, lower end in FIG. 10) and the upper end of the lower spiral 412 (right end in FIG. 9A, upper end in FIG. 10) are aligned. At this time, the upper end of the lower spiral 412 is mounted on the lower end of the upper spiral 411. Next, the upper spiral 411 and the lower spiral 412 are rotated in opposite directions to each other about the spiral axis so that the lower end 411A of the upper spiral 411 and the upper end 412A of the lower spiral 412 are overlapped by one turn.

  Since the winding pitch is different between the upper spiral 411 and the lower spiral 412, as shown in FIGS. 9B and 10, it is actually that the lower end 411A and the upper end 412A are overlapped in one winding. It is a part of it.

FIG. 11 is an enlarged front view of the ends of the upper and lower spirals connected to each other.
Next, for example, using a clamper, the lower end of the upper spiral 411 and the upper end 412A of the lower spiral 412 are sandwiched from above and below, and the upper end of the lower spiral 412 and the lower end 411A of the upper spiral 411 are sandwiched from above and below. As a result, as shown in FIG. 11, the winding pitch of the upper spiral body 411 is narrowed in one winding, while the winding pitch of the lower spiral body 412 is expanded, so that the winding pitch P becomes the same. As a result, substantially all of one roll will be superimposed on one another. Then, weld two or more places to each other. The lower end of the upper spiral 411 as a welding point so that the lower end of the upper spiral 411 is not separated from the upper end 412A of the lower spiral 412 and the upper end of the lower spiral 412 is not separated from the lower end 411A of the upper spiral 411. It is preferable to include two positions, the position and the position of the upper end of the lower spiral 412.

(Assembly of screw member 41)
Thus, the end portions of the upper spiral 411 and the lower spiral 412 are connected to each other. Next, assembly of the screw member 41 will be described.

  The screw member 41 is inserted into the cylindrical body 30 from the upper end port of the cylindrical body 30 with the lower spiral 412 first. The lower spiral body 412 passes through the upper cylinder 310, passes through the curved cylinder 330 of the lower cylinder 320, passes through the relay cylinder 322 of the lower cylinder 320, and reaches the reception position RP of gaming media in the reception cylinder 321. Thereby, the upper spiral body 411 is inserted into the upper cylinder 310, and the lower spiral body 412 is inserted into the lower cylinder 320. At this time, the mutually connected end portions of the upper spiral 411 and the lower spiral 412 are disposed in the straight portion (the range indicated by (HR) in FIG. 3) of the curved cylinder 330 in the lower cylinder 320. Let's do it.

Next, the shaft 43 in the upper spiral 411 is attached to the motor 42. As a result, the screw member 41 pivots within the cylinder 30 by the rotation of the motor 42. Thus, the assembly of the screw member 41 is completed.
The narrow wire is used for the lower spiral 412 because, for example, the lower spiral 412 is easily bent in a curved tube 330 having a bending radius R of about 250 mm.

  The inner diameter of the upper cylinder 310 and the lower cylinder 320 is about 94 mm. Therefore, the gap between the inner wall of the upper cylinder 310 and the outer diameter of the upper spiral 411 is approximately 14.5 mm (= (94 mm−65 mm) / 2). Further, the gap between the inner diameter of the lower cylinder 320 and the outer diameter of the lower spiral body 412 is about 18 mm (= (94 mm-58 mm) / 2). Although the gap (about 18 mm) in the lower spiral 412 is wider than the gap (about 14.5 mm) in the upper spiral 411, the lower spiral 412 transfers gaming media and the like in the straight cylinder 320A and the curved cylinder 330. Therefore, game media and the like can be transferred without any problem.

  Although the height H from the cylinder axis of the linear cylinder 320A to the upper edge of the waist plate 104 has been described as being constant in the embodiment, the invention is not limited thereto. The height H changes depending on the gaming machine island 1. When the height H changes, for example, it can be coped with by changing the length of the straight portion (indicated by (HR) in FIG. 3) of the curved cylinder 330.

  In the embodiment, the game ball has been described as an example of the game medium, but the object to be polished by the abrasive is not limited to this, and may be a medal used in a slot machine or the like.
